+# DECISIONS.md — ADR log
+
+Decisions inside the set architecture. D-NNN, never renumbered.
+
+- **D-001** — SDD+BDD+TDD adopted (2026-07-13). SPEC-system port:
+  numbered requirements in `specs/`, coverage classes
+  feature/test/manual, `tools/trace.py` enforcement in `make check`.
+  Process is binding — see SPEC-000.
+- **D-002** — BDD runs at the responder seam, not against live
+  services. `FakeModelResponder` scripts model output; Discord-event
+  behavior is unit-tested with mocked discord.py objects. Rationale:
+  Discord ToS forbids test-account automation and LLM output is
+  nondeterministic — a live-BDD lane would be flaky by construction.
+- **D-003** — Packaging = uv + pyproject only (2026-07-13). setup.py,
+  requirements.txt and pytest.ini removed; single source of truth,
+  locked via uv.lock. Python `>=3.11` floor keeps the kitchen host
+  (py3.11) deployable until FDB-016 lands.
+- **D-004** — openai SDK pinned `<2` (1.109.x). The v2 SDK migration
+  happens together with the FDB-005 envelope rewrite (structured
+  outputs / Responses API) — one breaking change, one test cycle,
+  instead of two.
+- **D-005** — `--strict-markers` stays on; requirement tags from
+  `.feature` files are registered as pytest markers dynamically in
+  `tests/conftest.py`.
+- **D-006** — FDB-005 stays on chat.completions + structured outputs;
+  the Responses API migration is deferred to FDB-007, where history
+  handling gets redesigned anyway — one conversation-state reshape
+  instead of two.
+- **D-007** — openai SDK bumped to 2.x together with the envelope
+  rewrite (supersedes the D-004 pin). `multiline` dependency dropped —
+  strict schema output made relaxed-JSON parsing dead code.
+- **D-008** — Operator runtime flags (pause/images/tasks/quiet) are
+  in-memory only; a restart resets to config defaults. Persistence
+  arrives with the FDB-011 task store if staff practice demands it.
+- **D-009** — `translate()` still keys off `fix-model` although the
+  repair path is gone; the whole translate-before-draw step dies in
+  FDB-009 (gpt-image-2 is multilingual). Not worth a config rename
+  for one phase. *(Closed 2026-07-13: FDB-009 deleted translate();
+  the fix-model config key is now fully dead and can be dropped from
+  live configs.)*
+- **D-010** — Persistence uses stdlib `sqlite3` via
+  `asyncio.to_thread`, not aiosqlite: no new dependency, and a
+  connection-per-operation with WAL is plenty at this message volume.
+- **D-011** — `save_history` replaces the channel's rows wholesale
+  per message instead of appending: histories are capped at
+  `history-limit` (~200-350 rows) and trims must be reflected;
+  correctness over micro-optimization.
+- **D-012** — Budget spend is *estimated* from configured per-token/
+  per-image prices, not fetched from the billing API: deterministic,
+  testable, no extra scopes. Dashboard hard limits (FDB-001) stay the
+  outer safety net; this ledger is the inner, immediate one. User
+  image quota counts at grant time (reservation), global image spend
+  at generation time.
+- **D-013** — `!forgetme` v1 purges history rows only; the
+  single-string channel memory cannot be selectively cleaned. Full
+  fact-level erasure ships with FDB-007 structured memory — stated in
+  the user-facing confirmation, not hidden. (Superseded by D-014:
+  erasure now covers facts, observations and episode traces.)
+- **D-016** — The reply/ignore classifier fails open (BEH-03): a
+  broken classifier must never mute the bot; the budget gate already
+  bounds spend. Its verdict gates BEFORE the main call, the
+  envelope's answer_needed still gates after — two independent nets.
+- **D-017** — All human-behavior knobs default to off/v3.0.0
+  semantics; behavior changes are config rollouts per deployment, not
+  code flips. The classifier's `factual` flag is the only coupling
+  (delay bypass) and defaults to false without a classifier.
+- **D-015** — Deploys are push-based from the dev machine
+  (`git archive <tag> | ssh`), not pull-based: no deploy keys or git
+  state on the hosts, the artifact is exactly the tag tree, untracked
+  live config survives in-place extraction. Trade-off: deploys need
+  the dev machine; acceptable for a one-operator project.
+- **D-014** — Structured memory (FDB-007): observations are the only
+  consolidation feed (independent of history trimming); consolidation
+  returns NEW facts only (no wholesale rewrite — the lossiness of the
+  old memoize path is exactly what we're removing); self-authorship
+  is enforced in code (fact subject must be an observation author),
+  not just in the prompt; memory reads run on the loop (small indexed
+  SQLite queries), writes off-loop. Legacy memory strings survive as
+  episodes; the memory table stays as a read-only legacy fallback for
+  deployments without memory-model.

+Feature: Response envelope handling
+  The responder parses the model's JSON envelope and decides what the
+  bot says, where, and whether staff is alerted. (SPEC-001)
+
+  Background:
+    Given a responder with history limit 10
+
+  @ENV-01
+  Scenario: Model answer reaches the user
+    Given the model answers with answer "Hei! Velkommen." and answer_needed "true"
+    When user "alice" sends "Hei bot" in channel "chat"
+    Then the response answer contains "Hei! Velkommen."
+    And the response is marked as needed
+
+  @ENV-02
+  Scenario: Suppressed answer stays silent
+    Given the model answers with answer "irrelevant musing" and answer_needed "false"
+    When user "alice" sends "talking to bob" in channel "chat"
+    Then the response is not marked as needed
+
+  @ENV-03
+  Scenario: Staff note forces delivery
+    Given the model answers with answer "Et oyeblikk!" and staff note "Guest at table 4 needs a waiter"
+    When user "guest" sends "Can somebody help us?" in channel "chat"
+    Then the response staff note is "Guest at table 4 needs a waiter"
+    And the response is marked as needed
+
+  @ENV-04
+  Scenario: Direct messages are always answered
+    Given the model answers with answer "Svar." and answer_needed "false"
+    When user "alice" sends "hei" directly to the bot
+    Then the response is marked as needed
+
+  @ENV-05
+  Scenario: Short-path rules skip the model
+    Given a short-path rule for channels "spam.*" and users "bob.*"
+    When user "bobby" sends "noise noise" in channel "spam-corner"
+    Then the model was not called
+    And the response is empty
+    And the history contains the message from "bobby"
+
+  @ENV-07
+  Scenario: History is trimmed to the limit
+    Given a responder with history limit 4
+    And 6 prior history entries in channel "chat"
+    And the model answers with answer "ok" and answer_needed "true"
+    When user "alice" sends "hei" in channel "chat"
+    Then the history length is at most 4
+
+  @ENV-08
+  Scenario: Markdown links are unwrapped
+    Given the model answers with answer "Se [menyen](https://fjerkroa.example/meny) her" and answer_needed "true"
+    When user "alice" sends "meny?" in channel "chat"
+    Then the response answer contains "https://fjerkroa.example/meny"
+    And the response answer does not contain "[menyen]"
+
+  @ENV-09
+  Scenario: Missing channel falls back to the message channel
+    Given the model answers with answer "ok" and no channel
+    When user "alice" sends "hei" in channel "kitchen-talk"
+    Then the response channel is "kitchen-talk"

+# SPEC-000 — Development process (binding)
+
+This repo is developed spec-driven + behaviour-driven + test-driven.
+
+## The three loops
+
+1. **Spec-driven**: every behavior exists first as a numbered
+   requirement (`<AREA>-NN`) in `specs/SPEC-NNN-*.md`. No code without
+   a requirement. Requirements are never deleted — a dead requirement
+   is marked `(withdrawn: <successor or reason>)` in its title line
+   and keeps its ID forever.
+2. **Behaviour-driven**: every *user-visible* requirement gets at
+   least one Gherkin scenario tagged `@<ID>` in `features/*.feature`,
+   executed by pytest-bdd.
+3. **Test-driven**: implementation starts at a red test. Unit tests
+   cover the non-visible requirements (arithmetic, invariants,
+   parsing).
+
+Change flow: spec change → feature/test red → implementation green →
+refactor.
+
+## Requirement format
+
+```
+### ENV-01 — Model answer reaches the user (coverage: feature)
+
+Normative statement first. Rationale after.
+```
+
+Coverage classes:
+
+- `feature` — needs an `@<ID>` tag in some `.feature` file.
+- `test` — the ID must appear in a test file (docstring or comment
+  of the covering test).
+- `manual` — needs a row in `manual-verification.md` with date and
+  result before the increment demo.
+
+## Enforcement
+
+`tools/trace.py` (stdlib-only) runs in `make check` (and `make
+trace`). It fails the build when a declared requirement lacks its
+coverage class artifact, when a feature tag references an undeclared
+ID, or when an ID is declared twice. Code fences in spec files are
+ignored by trace (the example above does not declare ENV-01).
+
+## Test substrate
+
+BDD scenarios run against the **responder seam**: a
+`FakeModelResponder` subclass with scripted model output — no live
+Discord, no live OpenAI (see DECISIONS.md D-002). Discord-event
+behavior is covered by unit tests with mocked discord.py objects.
+
+## ADRs
+
+Decisions inside the set architecture go to `DECISIONS.md` as
+`D-NNN — title — one-paragraph rationale`. The stack itself is not
+re-litigated there.
+
+## Spec map
+
+- SPEC-000 process (this file, no IDs)
+- SPEC-001 responder + envelope — ENV-NN
+- SPEC-002 memory — MEM-NN (lands with FDB-007)
+- SPEC-003 safety/privacy/abuse — SAF-NN (lands with FDB-014)

+# SPEC-001 — Responder + response envelope
+
+Characterization of the current (v2) responder contract in
+`fjerkroa_bot/ai_responder.py`. The model answers with a JSON
+envelope: `answer`, `answer_needed`, `channel`, `staff`, `picture`,
+`picture_edit`, `hack`. FDB-005 will replace the transport of this
+contract (structured outputs); the *behavioral* requirements below
+survive that change unless marked otherwise.
+
+### ENV-01 — Model answer reaches the user (coverage: feature)
+
+When the model envelope carries a non-empty `answer` and
+`answer_needed` is true, `AIResponder.send()` returns an `AIResponse`
+with that answer text and `answer_needed == True`. This is the core
+loop: user talks, bot answers.
+
+### ENV-02 — Suppressed answer stays silent (coverage: feature)
+
+When the model envelope sets `answer_needed` to false (and the
+message is not direct, mentions nobody, and no staff note is set),
+the returned `AIResponse` has `answer_needed == False`. The bot may
+observe without butting in.
+
+### ENV-03 — Staff note forces delivery (coverage: feature)
+
+When the envelope carries a non-null `staff` text and a non-null
+`answer`, the returned response preserves the staff text and has
+`answer_needed == True`. Staff alerts must never be silently
+dropped.
+
+### ENV-04 — Direct messages are always answered (coverage: feature)
+
+When the incoming `AIMessage` is marked `direct` and the model
+returns a non-null answer, `answer_needed` is forced to `True`
+regardless of the model's own `answer_needed`. A user addressing the
+bot directly gets a reply.
+
+### ENV-05 — Short-path rules skip the model (coverage: feature)
+
+When a configured `short-path` `[channel-regex, user-regex]` pair
+matches the message, `send()` appends the message to history, trims
+history to the limit, persists it, and returns an empty response
+(answer `None`, `answer_needed False`) **without calling the model**.
+Cheap archival of noisy channels.
+
+### ENV-06 — Malformed model output is repaired (coverage: withdrawn — successor ENV-18)
+
+Withdrawn 2026-07-13 with FDB-005: strict structured outputs make the
+repair model obsolete. Malformed output now counts as a failed
+attempt — see ENV-18.
+
+### ENV-07 — History is trimmed to the limit (coverage: feature)
+
+After a completed exchange, `len(history) <= history-limit` holds.
+Trimming happens both before the model call and after appending the
+new question/answer pair.
+
+### ENV-08 — Markdown links are unwrapped (coverage: feature)
+
+In the final answer text, `[label](url)` becomes `url` and
+`@[label](url)` becomes `label`. Discord renders raw URLs; markdown
+link syntax from the model reads as noise.
+
+### ENV-09 — Missing channel falls back to the message channel (coverage: feature)
+
+When the envelope `channel` is null/none/empty, the response channel
+is the channel the message came from.
+
+### ENV-10 — Dynamic context reaches the system prompt (coverage: test)
+
+The system message carries the current date, time, news (when the
+configured file exists) and the memory block (legacy string while
+structured memory is inactive, see MEM-10). Since FDB-008 these live
+in a context suffix, not inline — see ENV-20; legacy `{date}`,
+`{time}`, `{news}`, `{memory}` placeholders in operator templates are
+stripped.
+
+### ENV-21 — Tool calls disable reasoning effort (coverage: test)
+
+When function tools are attached to a chat call, the call carries
+`reasoning_effort` (config `reasoning-effort`, default `"none"`) —
+gpt-5.6 models reject tools + reasoning on chat/completions with a
+400 otherwise (found live on ggg 2026-07-13: IGDB tools made Luma
+mute after the Luna cutover). Tool-less calls stay untouched.
+
+### ENV-20 — Persona prefix is byte-stable (coverage: test)
+
+`message()` renders the system message as: static persona text
+(config template with all dynamic placeholders removed) followed by a
+`## Context` suffix holding date, time, news and memory. Two calls in
+the same channel produce byte-identical persona prefixes — the prompt
+cache can actually hit (the old inline `{date}`/`{time}` substitution
+invalidated it every minute).
+
+### ENV-11 — Per-channel history shrink prefers busy channels (coverage: test)
+
+`shrink_history_by_one()` removes the oldest entry whose channel has
+more than `history-per-channel` (default 3) entries; when no channel
+exceeds the cap, the oldest entry overall is removed.
+
+### ENV-12 — Exhausted retries raise, attempts are spaced (coverage: test)
+
+When the model returns no usable answer three times in a row,
+`send()` raises `RuntimeError`. Consecutive attempts are separated by
+an exponential-backoff sleep — failures never hammer the API
+back-to-back (D1).
+
+### ENV-13 — Reaction-clear events are recorded (coverage: test)
+
+`on_reaction_clear(message, reactions)` — the discord.py signature —
+records the clearing in the channel's memory. (D7: the previous
+handler declared `(reaction, user)` and crashed on dispatch.)
+
+### ENV-14 — update_memory persists its argument (coverage: withdrawn — successor SPEC-002)
+
+Withdrawn 2026-07-13 with FDB-007: the per-answer memory rewrite
+(`update_memory`/`memoize`) is deleted; structured memory (MEM-01+)
+replaces it. The D12 defect died with the code.
+
+### ENV-15 — retry-model is used after a rate limit (coverage: test)
+
+After a rate-limited attempt, the next `chat()` attempt uses the
+configured `retry-model` instead of `model`; a successful attempt
+switches back. (D2: the fallback was assigned to a local and never
+took effect.)
+
+### ENV-16 — Model calls are never served from a disk cache (coverage: test)
+
+`openai_chat`/`openai_image` call the client every time. The pickle
+response cache (`openai_chat.dat`) is a test-era artifact and must
+not exist in the production path (D3/D4).
+
+### ENV-17 — IGDB tool execution runs in a worker thread (coverage: test)
+
+`_execute_igdb_function` executes the synchronous IGDB library off
+the event loop (worker thread), returning identical results. The
+event loop keeps serving Discord events during lookups (D5).
+
+### ENV-18 — Malformed or refused output is a failed attempt (coverage: test)
+
+Model output is requested as schema-validated JSON (strict structured
+outputs). Output that still fails to parse, or a model refusal,
+counts as a failed attempt (backoff + retry per ENV-12) — there is no
+repair model, no `fix()` path, no relaxed-JSON fallback. Replaces
+ENV-06.
+
+### ENV-19 — The envelope schema is pinned (coverage: test)
+
+Every chat call carries `response_format` = strict JSON schema named
+`envelope` with exactly the fields `answer`, `answer_needed`,
+`channel`, `staff`, `picture`, `picture_count` (since FDB-009,
+IMG-02), `picture_edit`, `hack` — all required,
+`additionalProperties: false`, nullable where the protocol allows
+null. Tool-followup calls carry the same format.

+# SPEC-002 — Structured memory
+
+Replaces the single-string per-answer LLM rewrite (lossy, O(convo)
+cost — the old `memoize` path). Layers, simplified per plan v4:
+**user facts** (durable, provenance-tracked), **pinned facts**
+(operator-set, global or per channel), **episodes** (rolling channel
+summaries with decay). Channel-facts deferred until recall proves
+insufficient. Raw feed = **observations** (messages, reactions,
+edits, deletes); an async consolidation pass turns observations into
+facts + episodes. The memory system is active only when both a store
+(`history-directory`) and a `memory-model` are configured — otherwise
+the legacy memory string is used read-only (MEM-10).
+
+### MEM-01 — Events become observation rows (coverage: test)
+
+User messages, bot answers, reactions (add/remove/clear), edits and
+deletes are recorded as observation rows (channel, user, kind,
+content excerpt) — cheap writes, no LLM call per event.
+
+### MEM-02 — Consolidation is batched, never per message (coverage: test)
+
+Consolidation triggers when `memory-consolidate-every` (default 20)
+unconsumed observations have accumulated for a channel; it runs as a
+background task guarded by a lock (no overlapping runs), consumes the
+observations it processed, and leaves them in place when the model
+call fails (retry next trigger).
+
+### MEM-03 — Only self-authored facts persist (coverage: test)
+
+The consolidator stores a fact only when its subject user is among
+the authors of the consumed observations, with provenance
+`source='self'`; facts the model attributes to absent third parties
+are discarded and logged. Operator pins carry `source='operator'`.
+"Bob says Alice likes X" must never become Alice's profile
+(review consensus C2).
+
+### MEM-04 — Recall is participant-scoped (coverage: test)
+
+The memory block assembled into the system prompt contains: pinned
+facts (global + this channel), user facts of **conversation
+participants only** (current author + authors in the recent history
+tail), and the channel's recent episodes. Facts of non-participants
+never enter the prompt — the model cannot leak what it cannot see.
+
+### MEM-05 — Episodes decay (coverage: test)
+
+At most `memory-episodes-per-channel` (default 10) episodes are kept
+per channel; consolidation drops the oldest beyond the cap.
+
+### MEM-06 — User facts have a retention limit (coverage: test)
+
+Facts not updated within `memory-fact-retention-days` (default 180)
+are purged during consolidation. Durable is not indefinite (GDPR
+storage limitation).
+
+### MEM-07 — Staff review and edit memory (coverage: test)
+
+Staff commands: `!bot memory <user>` lists the user's facts with ids;
+`!bot forget-fact <id>` deletes one; `!bot pin <channel|global>
+<fact>` adds an operator pin; `!bot unpin <id>` removes one.
+
+### MEM-08 — Legacy memory strings migrate to episodes (coverage: test)
+
+Schema v3 migration copies existing per-channel memory strings into
+an episode row each; pickle migration does the same. Deployments keep
+their accumulated context through the upgrade.
+
+### MEM-09 — !forgetme erases facts, observations and episode traces (coverage: test)
+
+`!forgetme` now deletes the user's facts, their observation rows, and
+episodes mentioning the user's name — in addition to the SAF-08
+history purge. This completes the erasure that SAF-08 v1 could not.
+
+### MEM-10 — Memory system off degrades gracefully (coverage: test)
+
+Without `memory-model` (or without a store) no observations are
+written, no consolidation runs, and `{memory}` falls back to the
+legacy memory string — no crash, no behavior change for
+unconfigured deployments.

+# SPEC-003 — Safety, privacy + abuse hardening
+
+FDB-005 lands the injection-defense subset (the old `hack`
+self-report was the only defense — S4). Consequential actions are
+gated *outside* the model: the model proposes, deterministic code
+disposes. Quotas, budget caps, memory policies and GDPR controls
+follow with FDB-014 (SAF-10+, reserved).
+
+### SAF-01 — Model-proposed channel routing is allowlisted (coverage: test)
+
+A model-proposed answer channel is honored only when it is in the
+allowed set: config `allowed-channels` when set, otherwise the
+channels already named in config (`chat-channel`, `staff-channel`,
+`welcome-channel`, `additional-responders`). Anything else falls back
+to the origin channel and is logged. Prompt injection must not be
+able to redirect the bot into arbitrary channels.
+
+### SAF-02 — Outbound messages cannot ping (coverage: test)
+
+The bot is constructed with `allowed_mentions = none`: no user, role
+or @everyone/@here pings in any outbound message, regardless of what
+the model emits.
+
+### SAF-03 — External text is sanitized before prompting (coverage: test)
+
+Text from external sources injected into prompts or tool results —
+news-feed content and IGDB results — passes `sanitize_external_text`:
+control characters stripped, `@everyone`/`@here` neutralized with a
+zero-width space, length capped (default 4000 chars). RSS headlines
+and game descriptions are attacker-influenced input.
+
+The `hack` envelope field remains as an advisory signal (logged,
+staff-notified) but is no longer the defense.
+
+### SAF-10 — Model calls carry a hashed user identifier (coverage: test)
+
+Chat calls pass `safety_identifier` = a short SHA-256 digest of the
+message author's name — OpenAI-side abuse tracing without shipping
+raw Discord identities (Codex review recommendation).
+
+### SAF-04 — Hard daily budget, fail-closed (coverage: test)
+
+When `daily-budget-usd` is configured and today's estimated spend
+reaches it, no further model or image calls happen: the responder
+refuses before calling the API, and the bot answers nothing until
+midnight. Staff get exactly one alert per day about the silence.
+Cost estimation uses `price-input-per-m` (default 1.0),
+`price-output-per-m` (default 6.0) and `price-per-image` (default
+0.05). A budget of 0 means fully silent — fail-closed by
+construction.
+
+### SAF-05 — Usage is metered and survives restarts (coverage: test)
+
+Token counts (prompt/completion) from every model call and every
+generated image are recorded per calendar day; with a store
+configured the counters persist across restarts (usage table,
+schema v2).
+
+### SAF-06 — Per-user daily message quota (coverage: test)
+
+When `user-daily-messages` is configured, messages beyond the cap
+from one user on one day are ignored (logged, no model call). The
+`system` user (bot-initiated flows) is exempt.
+
+### SAF-07 — Per-user daily image quota (coverage: test)
+
+When `user-daily-images` is configured, picture requests beyond the
+user's daily cap are stripped from the response (the text answer
+still goes out).
+
+### SAF-08 — !forgetme purges a user's history (coverage: test)
+
+`!forgetme` removes the requesting user's messages from all live
+responder histories and from the store, then confirms in-channel.
+Since FDB-007 the purge extends to memory itself — facts,
+observations and episode traces (MEM-09).
+
+### SAF-09 — !privacy states the data practice (coverage: test)
+
+`!privacy` answers with the configured `privacy-notice` (a default
+notice ships in code): what is stored, that `!forgetme` exists.
+Works even while the bot is paused.

+# SPEC-004 — Image generation
+
+Generation on `image-model` (default `gpt-image-2`), base64 end to
+end — no URL downloads, no expiring CDN links in the generation path.
+Optional knobs: `image-size` (default 1024x1024), `image-quality`
+(passed through only when set). The Leonardo path stays behind
+`leonardo-token` until parity is confirmed, then dies. The input
+pipeline (attachment cache, vision, edit/remix) is FDB-010 / IMG-10+.
+
+### IMG-01 — Images arrive as base64 buffers (coverage: test)
+
+`draw_openai(description, count)` requests `count` images and returns
+a list of decoded image buffers straight from the API response; every
+generated image is metered in the ledger (SAF-05).
+
+### IMG-02 — The envelope carries picture_count (coverage: test)
+
+The envelope gains `picture_count` (integer). `post_process` clamps
+it to 1..4 and defaults to 1 when absent (legacy history entries,
+old-model output). ENV-19's field list is revised accordingly.
+
+### IMG-03 — Multiple images, one message (coverage: test)
+
+`picture_count` images are attached as multiple files to a single
+Discord send (the last part when the answer is split, per BEH-06).
+
+### IMG-04 — Legacy image models degrade safely (coverage: test)
+
+When `image-model` is not a `gpt-image-*` model (e.g. `dall-e-3`),
+the count is clamped to 1 and `response_format="b64_json"` is
+requested explicitly (gpt-image models return base64 natively and
+reject the parameter).
+
+### IMG-05 — Picture prompts go to the API untouched (coverage: test)
+
+The translate-before-draw step is deleted: the model's picture prompt
+reaches the image API verbatim (current image models handle
+Norwegian/German natively). The `translate()` method and its
+`fix-model` dependency are gone (closes D-009).
+
+## Input pipeline (FDB-010)
+
+Attachments live in a content-hash cache
+(`<history-directory>/images/<sha256>.<ext>`, index in the store,
+schema v4). Active only with a store; without one the legacy CDN-URL
+path remains.
+
+### IMG-10 — Attachments are ingested at message time (coverage: test)
+
+Every image attachment is downloaded immediately (timeout, size cap
+`image-max-bytes` default 8 MB) and stored under its content hash.
+Only sniffed png/jpeg/gif/webp bytes are accepted — extension and
+declared MIME are ignored (attacker-controlled). Rejected content is
+dropped and logged (D11 root fix + cache-abuse hardening).
+
+### IMG-11 — Vision reads from the cache, never CDN URLs (coverage: test)
+
+Vision parts are `data:` URLs built from cached bytes. Discord's
+signed, expiring CDN URLs never reach the model or the history.
+
+### IMG-12 — The cache is capped and aged (coverage: test)
+
+`image-cache-mb` (default 500) LRU-evicts oldest-first;
+`image-cache-ttl-days` (default 90) ages entries out. Eviction always
+removes file and index row together.
+
+### IMG-13 — picture_edit edits the newest channel images (coverage: test)
+
+`picture_edit=true` calls `images.edit` with up to the 4 newest
+cached images of the answer channel as inputs (API max is 16; 4 keeps
+prompts sane). An empty cache falls back to plain generation — the
+flag alone must never fail a reply.
+
+### IMG-14 — Deletion propagates to the cache (coverage: test)
+
+Deleting a Discord message purges its cached images; `!forgetme`
+purges all of the user's images — files and rows (extends
+SAF-08/MEM-09).
+
+### IMG-15 — Generated images join the cache (coverage: test)
+
+Bot-generated images are ingested like uploads (user `assistant`), so
+"make a variant of that" remix chains work on the bot's own output.
+
+### IMG-16 — The prompt announces editable images (coverage: test)
+
+When the answer channel has cached images, the context suffix states
+how many and that `picture_edit=true` edits the newest — the model
+cannot use a capability it does not know about.

+# SPEC-006 — Staff / operator controls
+
+Staff operate the bot from the staff channel without SSH. Runtime
+flags live in memory — a restart resets to config defaults (D-008).
+The staff-alert path is a tested contract: alerts are the
+business-critical feature on the restaurant deployment.
+
+### OPS-01 — Staff commands only work in the staff channel (coverage: test)
+
+`!bot …` commands are honored only when sent in the configured staff
+channel. In any other channel the text is treated as a normal
+message.
+
+### OPS-02 — Pause and resume (coverage: test)
+
+`!bot pause` stops all public replying (messages are ignored, no
+model calls); `!bot resume` restores it and clears quiet mode. Staff
+commands keep working while paused.
+
+### OPS-03 — Image kill-switch (coverage: test)
+
+`!bot images off` drops the picture part of any response before
+generation (answer text still goes out); `!bot images on` restores.
+
+### OPS-04 — Quiet mode with auto-resume (coverage: test)
+
+`!bot quiet <minutes>` silences public replies for N minutes, then
+the bot resumes by itself. Friday-service panic button that cannot be
+forgotten.
+
+### OPS-05 — Status report (coverage: test)
+
+`!bot status` answers in the staff channel with the current flags
+(replies / images / tasks / remaining quiet time).
+
+### OPS-06 — Keyword-forced staff alerts (coverage: test)
+
+When a user message matches any configured `staff-alert-keywords`
+regex and the model set no staff note, a staff alert is forced with
+user + message excerpt. Alerting must not depend solely on the
+model's judgement.
+
+### OPS-07 — Staff alerts are rate-limited (coverage: test)
+
+At most `staff-alert-max-per-hour` (default 10) alerts reach the
+staff channel per rolling hour; excess alerts are logged. An
+injection or a glitch must not be able to flood staff.
+
+### OPS-08 — Lost staff alerts are logged (coverage: test)
+
+When a staff alert cannot be delivered (staff channel unresolved),
+the alert text is written to the error log — never silently dropped.
+
+### OPS-09 — Self-tasking kill-switch (coverage: test)
+
+`!bot tasks off` disables bot-initiated posting (today: the boreness
+loop; later: the FDB-011 scheduler); `!bot tasks on` restores.
+Bot-initiated posts also respect pause/quiet.
+
+### OPS-11 — Pins are listable (coverage: test)
+
+`!bot pins` answers with all pinned facts and their ids (global +
+per-channel) — without it, `!bot unpin <id>` required guessing ids.
+
+### OPS-10 — Spend report (coverage: test)
+
+`!bot spend` answers in the staff channel with today's estimated
+spend in USD, token and image counts, and the configured budget.
+Management sees the cost, not just the cap.

+# SPEC-007 — Deploy + hosts
+
+Two uberspace hosts, one release: **fjerkroa** (service `kroa`,
+config `kroa.toml`) and **ggg** (service `luma`, config `ggg.toml`).
+Deploys are push-based from the dev machine — `git archive <tag>`
+over ssh, no repo credentials on the hosts (D-015). Coverage here is
+`manual`: rows in `manual-verification.md` with date + result.
+
+### DEP-01 — Deploys go by tag, in place, configs survive (coverage: manual)
+
+`deploy/deploy.sh <host> <tag>` refuses unknown hosts and refs that
+are not tags. The tag's tree is extracted over `~/fjerkroa_bot` —
+untracked files (live TOML config, `history/`, news snapshot) are
+never touched. Dev-on-host drift ends here: hosts run tag content
+only.
+
+### DEP-02 — Per-host service map (coverage: manual)
+
+fjerkroa → supervisord program `kroa`, config `kroa.toml`; ggg →
+program `luma`, config `ggg.toml`. The script owns this map; restart
+via `supervisorctl restart <service>`.
+
+### DEP-03 — Pre-deploy state backup (coverage: manual)
+
+Before the restart, every `bot.db` under `~/fjerkroa_bot` is copied
+to `bot.db.pre-<tag>` on the host. Schema migrations are
+forward-only (PER-06) — rolling back past a schema bump means
+restoring this backup.
+
+### DEP-04 — Smoke test gates the deploy (coverage: manual)
+
+After restart the script fails loudly unless the service reports
+RUNNING and the log shows a fresh Discord login line. On failure the
+operator instruction is printed: deploy the previous tag (DEP-06).
+
+### DEP-05 — No kroa deploys during service hours (coverage: manual)
+
+Deploys to fjerkroa between 11:00 and 22:00 Europe/Oslo are refused
+unless `DEPLOY_FORCE=1` is set. The restaurant does not beta-test
+during dinner.
+
+### DEP-06 — Rollback is a deploy of an older tag (coverage: manual)
+
+`deploy.sh <host> <previous-tag>` is the rollback path; when the
+schema version moved, restore the DEP-03 backup first. Venv is
+rebuilt from the tag's pyproject either way.

+TOML config per deployment (`kroa.toml`, `ggg.toml` — both untracked;

+`FjerkroaBot.load_config`, hot-reloaded by a watchdog observer
+(defect D9 — reload race — is tracked in FDB-004 and will refine
+these requirements).
+
+### CFG-01 — TOML config loads into a plain dict (coverage: test)
+
+`FjerkroaBot.load_config(path)` parses the TOML file and returns its
+top-level table as a dict; responders read raw keys from it.
+
+### CFG-02 — Per-channel system prompt override (coverage: test)
+
+A responder bound to channel `X` uses `config["X"]` as its system
+prompt when that key exists, else `config["system"]`. One deployment
+can speak differently per channel.
+
+### CFG-03 — Missing news file degrades silently (coverage: test)
+
+When `news` points to a non-existent file, the context suffix simply
+carries no news section (no crash, no literal placeholder — revised
+with ENV-20; previously the `{news}` placeholder stayed literal).
+
+### CFG-04 — Config hot-reload applies on the event loop (coverage: test)
+
+The watchdog observer thread never mutates live config references
+itself: a detected change is loaded, then the swap of `bot.config`
+and all responder `.config` references is scheduled onto the event
+loop (`call_soon_threadsafe`), so no request ever reads a
+half-swapped config (D9). Before the loop runs (startup), the swap
+applies directly — there are no concurrent readers yet.

+dependency (D-010). Without `history-directory` in config the bot
+runs memory-only, as before.
+
+### PER-01 — History survives restarts (coverage: test)
+
+History entries written through the store are returned, in order and
+per channel, by a fresh store instance on the same database file.
+
+### PER-02 — Memory survives restarts (coverage: test)
+
+The per-channel memory string written through the store is returned
+by a fresh store instance on the same database file.
+
+### PER-03 — Existing pickles migrate exactly once (coverage: test)
+
+On responder start, when the database holds no rows for the channel
+and legacy pickle files exist, their content is imported and the
+pickle files are renamed to `*.migrated` (kept for rollback). A
+second start does not re-import. Users keep their history through
+the cutover (review consensus: migration is a decision, not an
+accident).
+
+### PER-04 — Database hygiene (coverage: test)
+
+The database runs in WAL journal mode, carries `PRAGMA user_version`
+= the store's current schema version for the migration/rollback
+policy, and the file is chmod 0600 (it stores conversation data).
+
+### PER-06 — Schema migrations run forward automatically (coverage: test)
+
+Opening a database with an older `user_version` applies the missing
+migration steps in order (v1 → v2 adds the usage table) and preserves
+existing rows. Deploy rollback policy: never roll binaries back past
+a schema bump without restoring the pre-deploy backup.
+
+### PER-05 — Writes run off the event loop (coverage: test)

+History and memory persistence happen in a worker thread
+(`asyncio.to_thread`) — a slow disk cannot stall Discord event
+handling (D6).

+# SPEC-010 — Human-behavior layer
+
+The bot should feel like a considerate participant, not an instant
+wall of text: it decides *whether* to speak with a cheap classifier
+instead of trusting the main model's self-report, paces its replies,
+splits long answers, and sometimes just reacts. All knobs are
+per-deployment TOML; every feature degrades to the previous behavior
+when its knob is unset (config-off = v3.0.0 semantics).
+
+### BEH-01 — Classifier gates non-direct replies (coverage: test)
+
+With `classifier-model` configured, every non-direct user message
+first passes a cheap classification call (reply yes/no, factual
+yes/no, optional reaction emoji). `reply=false` means no main-model
+call happens at all — this is the boreness suppressor and the
+butting-into-conversations fix (replaces trusting `answer_needed`
+alone; the envelope flag still applies afterwards as second gate).
+
+### BEH-02 — Direct messages bypass the gate (coverage: test)
+
+Mentions and DMs never go through the classifier — someone addressing
+the bot always reaches the main model. Welcome and bot-initiated
+flows do not pass the gate either.
+
+### BEH-03 — Classifier failure fails open (coverage: test)
+
+A failed or unparseable classification (API error, budget refusal)
+falls through to the main model. Availability beats savings; the
+budget gate still protects spend.
+
+### BEH-04 — Reply pacing is typing-proportional (coverage: test)
+
+With `typing-chars-per-second` set (recommended 30), the typing
+indicator is held for `len(part) / cps` seconds per message part,
+capped at `typing-max-seconds` (default 8), before sending. Unset or
+0 = no pacing (v3.0.0 behavior).
+
+### BEH-05 — Factual answers skip the artificial delay (coverage: test)
+
+Messages the classifier tagged `factual` (opening hours, prices,
+addresses) are answered without the BEH-04 delay — utility beats
+theater exactly where users are waiting for information.
+
+### BEH-06 — Long answers are split (coverage: test)
+
+Answers longer than `split-threshold` chars (default 1200) are split
+at paragraph (then sentence) boundaries into at most
+`split-max-parts` (default 3) sequential messages, each under the
+Discord 2000-char limit (which unsplit answers would crash into
+today). Attached images go with the last part.
+
+### BEH-07 — Sometimes a reaction is the reply (coverage: test)
+
+When the classifier returns `reply=false` plus a reaction emoji, the
+bot adds that emoji to the user's message instead of staying fully
+silent. Zero main-model cost, human touch.
+
+### BEH-08 — Quiet hours stop bot-initiated posts (coverage: test)
+
+Within `quiet-hours = "HH:MM-HH:MM"` (host-local, may wrap midnight)
+`bot_initiated_allowed()` is false: no boreness, later no scheduler
+posts. Replies to users stay unaffected — a guest asking at 23:30
+still gets an answer.
